Explanation:
The final velocity at the cannon ball's maximum height is zero (). We can use the equation
No. Parallel branches have the same potential difference across them. A break in one does not affect the other.
Answer:
The speed of Lilac is 0.399c.
Explanation:
The size of spaceship Lilac measured at the rest position = 721 m
The length of Lilac when it passes Earth = 661 m
Below is the calculation for speed at which Lilac is moving.
Here, L, is the length of spaceship when it passes the earth.
is the length of spaceship measured at rest.
V is the speed.
I think the answer is A but i could be wrong
Answer:
Explanation:
The impulse-momentum theorem gives the impulse on an object to be equal to the change in momentum of that object. Since mass is maintained, the change in momentum of the basketball is:
, where is the mass of the basketball and is the change in velocity.
Since the basketball is changing direction, its total change in velocity is:
.
Therefore, the basketball's change in momentum is:
.
Thus, the impulse on the basketball is (two significant figures).
